Abstract (en)
[origin: EP1127825A2] This invention relates to an apparatus (1) for the transversal drawing of a film (2) in motion, comprising a pair of rollers (3, 4) rotating on parallel axes, fitted with toothed surface profiles (5, 6) capable of compentrating without touching each other and defining a wavy passage (7) for the film, where the rounded tips of the toothed profiles (5, 6) of the two rollers (3 and 4) define the points of application of the drawing action on the film (2).
